Upgrading to a newer version
Common extensions like the e-Commerce extensions are updated quite frequently. We recommend that you check, the version of the extension that is in use in your website at TYPO3 TER; you can verify which versions are available.
You can check extensions and the available versions in the Ext Manager. Choose Import extensions from the top menu and click on the Retrieve/Update button.
After the data update, you should choose Check for extension updates from the top menu. You will see a list of extensions that has the newest versions. If there are no newer versions of the extensions, this list will be empty.
You can check for the extension update manually too, using the TYPO3 TER website:
